| 摘要 |
<p>An object is that contact between an upper switch electrode and a lower switch electrode is not hindered. The present invention relates to a MEMS switch including a substrate; a structural layer with a beam structure in which at least one end is fixed to the substrate; a lower drive electrode layer and a lower switch electrode layer which are provided below the structural layer and on a surface of the substrate; and an upper drive electrode layer and an upper switch electrode layer which are provided on a surface of the structural layer, which is opposite to the substrate, so as to face the lower drive electrode layer and the lower switch electrode layer, respectively, in which the upper switch electrode layer is larger than the lower switch electrode layer.
